e.g. 10.0 – 3 significant figures; a decimal points exists. 0.0102000 – 6 significant figures; the leading zeroes are not significant, the trapped zero is and since there is a decimal point in the number, the trailing zeroes are significant.
Hereof, How do you divide sig figs? When dividing significant digits, the amount of significant figures in the final product is determined by the number of significant digits in the dividend and the divisor. The quotient can only have as many significant digits as the dividend or the divisor with the least amount of significant digits.
How many significant figures does 0.10 have? Least number of significant figures present in given data
For example, if the problem states that there is 20.0 mL of a 0.10 M Na(OH) solution, your final answer would have 2 significant figures because 20.0 has 3 sig figs and 0.10 only has 2.

What is a 3 significant figure? The third significant figure of a number is the digit after the second significant figure. This is true even if the digit is zero, and so on. … We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits.
How do you do sig figs with multiple operations?
How do you multiply and divide with sig figs? The following rule applies for multiplication and division: The LEAST number of significant figures in any number of the problem determines the number of significant figures in the answer. This means you MUST know how to recognize significant figures in order to use this rule.
How do you do sig figs with addition and multiplication? When you add or subtract, you assign significant figures in the answer based on the number of decimal places in each original measurement. When you multiply or divide, you assign significant figures in the answer based on the smallest number of significant figures from your original set of measurements.
How many significant figures are there in 12340?
Trailing zeroes in a number without a decimal point may or may not be significant. 12340 may have 4 significant digits or 5 significant digits. The only way to know for sure is to use scientific notation (1.2340 × 104 has 5 significant digits; 1.234 × 104 has 4 significant digits).
Also How many significant figures does 5200 have? 4. 5,200 – Two significant digits. There is no decimal place so the trailing zeros are simply placeholders and not-significant (see rule #4 above).
